PHOTOGRAPHIC DEVELOPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 622,141, dated March28, 1899.

Application filed July 8, 1898. Serial No. 685,398. (No model.)

will produce better negatives than the ordinary method of developingfilms.

Another object of the invention is to provide a film-developer by theuse of which all scratching of the films will be prevented and wherebyitwill not be necessary to cut the films until the negatives are bright.Furthermore, no complicated machinery is employed or any mechanismadapted to get out of order and that cannot be adjusted and manipulatedby any person of ordinary intelligence.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in both figures.

Figure 1 is a vertical section taken substantially on the line 1 1 ofFig. 2; and Fig. 2 is a front elevation of the device, a portion of thetray being in section.

The base A is a tray intended to hold the developing solution and isshown as of rectangular shape, although other shapes may be employed. Ineach side of the tray opposing slots and 11 are produced, the inner endsof the slots being made to face one another, and the slots are curved orinclined at the upper edges of the tray, their lower portions being moreor less horizontal. The slots 10 and 11 may be made to extend throughthe sides of the tray and are preferably formed in the inner faces onlyof said sides. Arms 12 are pivotally attached to the tray at each of itssides, ordinarily through the medium of suitable bolts 13 and thumb nuts1 1, and the arms 12 may be considered as a portion of tray is avoided.

the lower frame B. The arms 12 serve in a great measure to support asecond frame 0, the side pieces 15 whereof are pivoted upon a rod 16,which is passed through the upper ends of the said arms 12 and the sides15 of the upper frame, and between the sides 15 of the upper frame aspacing-sleeve 17 is located, the spacing-sleeve and rod constituting aportion of the bottom frame B. The rod 10 is usually provided with ahead at one end and a thumb-screw 18 at the opposite end.

The forward end of the upper frame 0 is closed by a cross-bar 19, andnear the said cross-bar a roller 20 is journaled, one trunnion whereofis provided with a crank-handle 21. The trunnions of the roller 20 arejour naled usually in slot-bearings 22 in the side bars or side pieces15 of the upper frame, as shown especially in Fig. 1.

In the slots 10 and 11 rollers 23 and 2st are journaled, and owing tothe peculiar formation of the slots 10 and 11 the rollers in operationwill work toward each other, and all tendency of the rollers to work outfrom the The film 25 to be developed is carried by the rollers 23 and2-1 and the upper roller 20. The film 25 is connected at its ends in anysuitable or approved manner to form an end less band or belt, and thisendless band or belt is carried over the upper roller 20 and under thelower or tray rollers 23 and 24,which serve as guides, and the saidguide-rollers are preferably so spaced as to bring each nega tiveconsecutively and completely into the developer contained in the tray.

It will thus be observed that a long roll of film negatives may beexpeditiously, conveniently, and evenly developed, and the frame is somade that it can beadjusted to accom modate a belt of films of anydesired length,- since the lower frame B may be carried forward orrearward and the upper frame 0 adjusted upward or downward, as occasionmay demand.

It is evident that the two frames may be folded together and the trayfolded within the frames, thus making a flat and neat package that willoccupy but little room.

Having thus described my invention, I claim as new and desire to secureby Letters Patent-- 1. A device for developing films consisting of atray, frames adjustable relative to each other and relative to the tray,the frames being supported from the tray, and rollers located within thetray and upon the frame, the said rollers being adapted as supports forthe film to be developed, as set forth.

2. A device for developing films, consisting of a tray, rollersremovably mounted in the tray, a frame pivoted to the tray, being adjustable forwardly and rearwardly, a second frame pivoted to theforwardly and rearwardly adjustable frame, the second frame havingvertical adjustment, and a roller carried in the second frame, occupyingsuch relation to the rollers in the tray that the tray-rollers and theframe-roller may combinedly support the endless belt of films, as andfor the purpose specified.

In a device for developing films, the combination, with a tray androllers journaled in thesaid tray, the rollers being spaced a sufficicntdistance apart to admit of a negative of predetermined size to be heldin the said tray, of adj ustably-connected frames, the said frameshaving adjustable connection with the said tray, and a roller carried byone of the frames, adapted in conjunction with the rollers in the trayto support a belt of films, for the purpose set forth.

4. The combination,with a developing-tray having slot-bearings havingcurved upper portions and substantially straight lower ends, and rollersthe trunnions of which are removably located in the said slot-bearings,of a frame pivoted to the said tray at a point between the rollers, alocking device for the frame, a second frame pivotally attached to theframe connected with the tray and being at a right angle to thetray-frame, a locking device located at the point of connection of thetwo frames, a roller located in the upper frame, and means for turningthe said roller, for the purpose specified.

ALBERT GOOD'ER.
